Logistic regression models for occurrence of HGD/adenocarcinoma in any synchronous polyp
| Multivariate logistic model | |||
|---|---|---|---|
| Parameter | n | OR (lower – upper 95 % CI) | p-value |
| Increase in size of large polyp (per 10 mm) | 352 | 1.14 (0.94–1.38) | 0.17 |
| Increase in age (per 5 years) | 0.97 (0.84–1.12) | 0.66 | |
| Female vs. male sex | 1.01 (0.53–1.86) | 0.98 | |
| Increase in number of synchronous polyps (per 1 polyp) | 1.16 (1.09–1.24) | <0.0001 | |
| large polyp with HGD or adenocarcinoma vs. other histology | 3.33 (1.77–6.35) | 0.0002 | |
| Location of large polyp in rectosigmoid colon vs. other location in the colon | 0.84 (0.40–1.67) | 0.62 | |
| Location of any synchronous polyp in the rectosigmoid colon vs. other location | 2.65 (1.44–5.0) | 0.002 | |
